IMPROVEMENT IN PRINTERS -QUO|NS.

Specification forming part of Letters Patent No. 40,081, dated September22, 1865.

To all whom it may concern:

Be it known that we, HIPPOLYTE A. MARI- NoNI and FRANoIs NOEL OHANDR,both ot' Paris, in the Empire of France, have invented anew and usefulImprovement in Quoins and Furniture for Locking up Forms of Type forPrinting; and we do hereby declare that the following is afull, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specication, in whichvFigure l is a plan of a chase containing a form of type locked up by ourinvention. Fig. 2 is alongitudinal section of the same perpendicular tothe face of the form. Fig. 3 is a side view of one of the quoins on alarger scale than Figs. l and 2. Fig. 4t is a transverse section of apiece of the furniture on a scale corresponding with Fig. 3. Fig. 5 is a'plan of a piece of furniture suit-able for small job-work. Fig. 6 is aview of a key for locking up and unlocking the form.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in the construction of the quoins in the form ofrollers with surrounding recessed teeth or cogs, and thel furniture withracks or series of teeth or cogs to gear with the said teeth orcogs onthe quoins, such quoins being applied to roll between the furniture andthe chase, or between two sticks of furniture and being turned by a keyto move them from a wider to a narrower portion of the taper spacebetween the furniture and the chase or between two pieces of furniture,and thereby made to tighten up the type in the page or pages and tightenup the page or pages in the chase.

lo enable others skilled in the art to make and use our invention, wewill proceed to describe it with reference to the drawings.

A A are the quoins, which may b e of brass or other metal, and may becast of the required form. a a are their recessed teeth or cogs, soarranged as to leave flange-like bearing-surfaces b b above and lbelowthem, the said surfaces formingportions of the periphery of a cylinder.The ends of the teeth a a are iust within the said surfaces b b, bywhich they are protected from contact with the chase G or with anyportion of the furniture but Jthe tacks or cogs provided thereon. Thedepth of these quoins corresponds with the depth of the chase andfurniture. c c are holes, of square or other suitable form, provided inthe centers of the quoins for the reception of the key D, Fig. 6.

E F represent furniture, consisting of a sidestick and a foot-stick,straight on the inner side which comes next the form cl d, and havingthe outer side, which comes next the quoins, formed with aseries ofinclinations, e c, which may all have one direction, as illustrated inE, or' opposite directions, as illustrated by F.

f f are the racks or series of teeth or cogs provided on the outer sidesof the furniture to gear with the teeth or cogs a a of the quoins, soconstructed and arranged as to allow the cylindrical bearing-surfaces bb of the quoins to bear upon the smooth surfaces e c above and belowthem. The straight sides of the furniture which come next the type inthe form are roughened or toothed, as shown at q in Fig. 5, to give it afirm hold upon thc exterior of the form. The piece of furniture shown inFig. 5,'it will be seen, has but one inclination, e, which may besufficient for very small forms. rllhe furniture may be made ofmalleable castiron, and the racks cast upon it.

To lock up the form the chase is put on and the furniture put into it inthe usual manner, and the quoins are then placed in the widest parts ofthe taper spaces h h, between the chase and furniture, and turned by thekeyD in the direction of the arrows shown upon them inFig. 1, when theirteeth or cogs a t roll upon the racks f fof the furniture, and theirsurfaces b b roll upony the smooth inclined surfaces e e, andv they arethereby forced into the narrowing portions of the spaces h h, and socaused to act in a similar manner to wed ges, and press the furnitureagainst the form, and so lock the type together and'loek it in thechase. To unlock the type it is only necessary to turn the quoins in theopposite direction.

In forms of more than one page in which the pages are separated by thefurniture and interposed quoins only, only one of the two pieces offurniture employed between two pages requires to be furnished with arack and the other may be a simple straight piece.

The advantages ofthis invention consists in the greater facility forms,and in the greater durability of the quonis.

What We eluim as our invention7 und de sire t0 secure by Letters Patent,isl The combination of tootlied oreoggeil roller l quoins and furniturehaving corresponding,

afforded for loeking,r up l racks, teeth7 or eogs, substantially asherein l described. HIIPLYTE AIGUSTE MAlINONI, l FRANQIS NDEL GIIANURE.
